I'm trying to understand load calculation and see if there is a faster way. If I am missing information to answer this question please let me know.
Scenario: You have 100A panel. You decide to go from gas range to electric range but you need an add a 220V 50Amp circuit to the breaker panel. Suppose there are 5 slots left for the sake of talking and plenty of room in the box. My understanding is the max of the 100A that's usable is 80% as a continuous load. Since some items are not continuous, how do we determine the max load here.
Questions:
a. How do I determine what amperage the house is currently using? I realize it may not use 80% but how do I figure this out?
b. What information do I need to determine whether or not I can add this breaker to the panel without going above 80%. Beyond turning the whole house on, what's the proper way to do this?
